The inventive device includes a box-shaped steel shell and rigid polyurethane foam which partially occupies the shell's interior so as to leave a compartment to be used for situation of a suspected explosive object. The compartment is accessed by a doored entrance which is provided in the shell. Some inventive embodiments include a polyethylene liner for foam wear protection, and/or a high-strength layer for attenuating explosive fragmentation. Foam bodies are carefully packed inside the compartment for separating the suspected explosive device from the doored entrance and for stabilizing the suspected explosive object during transit. Upon detonation, the foam pulverizes and the shell inelastically deforms into an ovaloid or cylindroid shape. The shell's edges and corners are convexly contoured for thwarting localized strain concentrations in the shell. The inventive device is implemented for a single explosive event, as distinguished from conventional explosive containment devices which are implemented on a repetitive basis. As compared with conventional devices, typical inventive embodiments are small, lightweight, portable and inexpensive; yet, unlike conventional devices, the invention's doored entrance and compartment are dimensioned to accommodate a large suspect package in its entirety, thereby obviating disassembly of the package.
